Legal Action Overview
Wolfspeed Inc, listed on NYSE under ticker WOLF, announced after the close of trading on Tuesday, 7 August 2026 that it had filed a patent infringement lawsuit against rival Navitas Semiconductor Corp (NASDAQ:NVTS). The complaint was lodged in the United States District Court for the Western District of North Carolina and asserts that Navitas’s products infringe a portfolio of Wolfspeed’s foundational gallium nitride (GaN) and silicon carbide (SiC) patents. The patents identified in the filing are U.S. Patent Nos. 8,169,005; 10,998,418; 10,886,396; 10,749,443; and 11,888,392.
Products Allegedly Infringed
According to the complaint, the infringing Navitas offerings include its GaN‑based field‑effect transistors – the GaNFast®, GaNSlim™ and GaNSafe® families – as well as its GeneSiC™ MOSFETs and SiCPAK® power modules. Navitas has not issued a public response to the allegations at the time of reporting.
Market Reaction
Wolfspeed’s shares closed the session down $3.47, an 8.79 % decline, at $36.00 on the NYSE, reaching an intraday low of $34.01. In after‑hours trading the stock recovered 0.64 % to $36.23. Navitas’s shares fell 8.14 % to $13.99 on the NASDAQ and remained relatively flat thereafter. The sell‑off occurred amid a broader decline in the chip sector.
Company Context
Wolfspeed, headquartered in Durham, North Carolina and formerly known as Cree, highlighted the filing as “decisive action to protect its foundational GaN and SiC intellectual property portfolio.” The company has invested heavily in SiC manufacturing capacity, viewing its IP portfolio as a competitive moat in the rapidly expanding power‑device market that serves electric‑vehicle drivetrains, renewable‑energy inverters and industrial power conversion systems.
Financial Metrics
At the close, Wolfspeed’s market capitalization was approximately $1.74 billion. The stock traded about 5.45 million shares on the day, below its three‑month average volume of 7.6 million shares. The price remains well under its 52‑week high of $80.82 but far above its 52‑week low of $1.16, reflecting a one‑year gain of more than 1,300 %.
Potential Outcomes
If the court upholds Wolfspeed’s claims, Navitas could be subject to injunctions on the identified product lines or required to pay royalties. Conversely, a dismissal of the suit would reinforce Navitas’s competitive position and could exert additional pressure on Wolfspeed’s share price. Investors are expected to monitor Navitas’s formal legal response and any subsequent court filings for further clarification of the dispute’s scope.
